Assessment of Kinect V2 for elbow range of motion estimation in people with haemophilia using an angle correction model

Abstract

Introduction The joint range of motion (ROM) is an important clinical parameter used to assess the loss of functionality resulting from joint bleedings in people with haemophilia. These episodes require a close follow‐up and, to decrease patients' hospital dependence, telemedicine tools are needed. Therefore, this study is aimed to analyse the validity of the Microsoft Kinect V2 sensor with corrected angle measurement to be used in the monitoring of elbow ROM in people with haemophilia. Methods A convenience sample of 10 healthy controls (CG) and 10 patients with haemophilia with elbow arthropathy (HG) participated in this study. Full ROM of elbow joints was measured in the frontal view with a 10‐degree sweep using: (a) a clinical goniometer; (b) the Kinect V2; (c) the Kinect V2 with angle correction; and (d) using a photograph. Bland‐Altman graphs (mean and 95% Limits of Agreement [LOA]) and Wilcoxon test were used to determine differences between measurements and groups. Results The angle‐corrected Kinect V2 measurement removed the skew in the original data, reducing the average errors from 7.9° (LoA = −10.3°; 26.0°; CG) and 9.5° (LoA = −7.9°; 26.9°; HG) to −0.1° (LoA = −8.1°; 7.9°; CG) and −0.7° (LoA = −10.7°; 9.3°; HG). Conclusions These error levels allow the use of Kinect V2 in the clinical practice. Kinect V2 with angle correction can complement the classical goniometry allowing an efficient and touchless measurement of ROM.

Automatic range of motion measurement via smartphone images for telemedicine examination of the hand

“…The former requires depth camera devices, like Microsoft Kinect, 22 Intel RealSense, 23 and Leap Motion, 18 and have been evaluated in home care and telerehabilitation of the upper limb. 24 – 26 However, these devices may not be available for every patient. The other method could extract key points from a single image via general cameras or smartphones.…”

Development of Joint Activity Angle Measurement and Cloud Data Storage System

“…Two physical therapy plans used to evaluate manual therapy-home exercises combined with educational courses-show that the two physical therapy plans could alleviate the elbow pain for hemophilia [20]. In [21], the ROM of the elbow joint was evaluated efficiently via a Microsoft Kinect v2 sensor with angle measurement calibration (for a contactless ROM measurement). In [22], researchers used a GoNet v2-combined computer with a Kinect sensor for the ROM measurement.…”
